“…The ranking of species with respect to drought vulnerability coincides with various other studies in central Europe (e.g., [74][75][76][77]). Our method is in line with the often applied relative transpiration index (RTI) [78,79] which accentuates absolute water availability. Müller [78] describes how to derive the RTI based on climatic water balance and available soil moisture, whose sum equals the site water budget used in this study.…”

Rapid climate change leads to significant shifts in the site-productivity relationship of tree species and alters abiotic and biotic risks well beyond classical rotation ages on many forest sites worldwide. Forest conversion may be an adequate measure to counter possible negative effects of climate change. Unfortunately, climate-driven changes in abiotic and biotic risks bear a significant source of intrinsic uncertainty inherent in climate projections. It is our goal to appraise uncertainty in species selection under drought stress, one of the most important risk factors for many forests. We derive a method to assess drought restrictions and demonstrate the uncertainty in the process of species selection by applying three climate scenarios. Furthermore, we interpret the consequences of climate uncertainty in the light of different management goals, i.e., a business-as-usual silviculture, a climate protection strategy favoring CO 2 sequestration and a biodiversity strategy increasing diversity. The methods are applied to two representative regions in the North German Plain. The results clearly show the strong need for adaptive planning when drought restrictions are considered. However, different silvicultural management objectives may alter the extent of adaptive planning. The uncertainty in the planning process arising from different underlying climate projections strongly depends on the regional site characteristics and on forest management strategy. In conclusion, it is most important in forest planning to clearly state the management goals and to carefully explore if the goals can be met under climate change and if the uncertainty due to climate projections significantly affects the results of species selection.

“…Actual transpiration, by contrast, is defined as the actual transpiration rate with stomatal opening adapted to the current drought stress conditions. A TI equal to 1 indicates that the water supply of the forest is optimal, whereas a TI value of less than 1 indicates temporary water deficiency (Wellpott et al 2005). Hammel & Kennel (2001) defined sites as having frequent water deficiency when the 25 th percentile of their daily TI values was below 0.95.…”

“…Drought represents a weather-specific phenomenon that affects forests to varying extents and may result in a long-term decrease in forest productivity (Bergès & Balandier 2010, Bertini et al 2011 or forest decline (Wellpott et al 2005, Bréda et al 2006, Briceno-Elizondo et al 2006, Anderegg et al 2013b. Over the last 30 years, Europe has been affected by a number of major drought events, most notably in 1976 (Northern and Western Europe), 1989 and 1991 (most of Europe - Mishra & Singh 2010).…”

“…Some drought stress indices incorporate topographic and edaphic variability to assess fine-scale soil water availability (Dyer 2009, Piedallu et al 2013). However, physiological indices, such as those related to soil water deficits (Zahner 1967) or transpiration rates (Zierl 2004, Wellpott et al 2005, have been shown to be better correlated with radial growth and enable biological interpretations of vegetation responses to climate (Michelot et al 2012, Tegel et al 2014.…”

Two drought stress indices were applied to managed as well as old-growth beech forests and gaps for the 2001 to 2013 period to aid in the development of an efficient tool for field water supply diagnosis. The relative extractable soil water (REW), which was calculated from the soil water content in the root zone, and the transpiration index (TI), calculated as the ratio between the actual and potential transpiration were used. Both indices were calculated on a daily basis using the water balance model BROOK90, which was fitted and tested using measured data on throughfall and soil water content. A sensitivity analysis apportioned to the input parameters of the drought stress indices was conducted to assess uncertainty. Both drought stress indices showed the greatest drought stress in the years 2009, 2003 and 2011, as also indicated by the Standardized Precipitation Evapotranspiration Index (SPEI) at the nearest meteorological station. However, drought stress intensity and duration differed between the indices and study sites. Greater water supply stress was shown in the forests than the gaps. Furthermore, the agreement among the indices was smaller for gaps compared with forests, which implies that careful index selection is needed when comparing water supply stresses in different stages of forest stand development. Due to the low amount of input data required and the parameters that can be measured with relative ease in the field, REW might be an efficient tool for field water supply diagnosis when analyzing the drought stresses of similar forest types and at unique stages of development. REW satisfactorily indicated drought stress in forests but to a lesser extent in gaps. TI demonstrated more consistent differences in drought stress between forests and gaps and therefore proved to be the appropriate index for a detailed analysis of drought stress variation between different stages of forest stand development. However, due to a greater number of required input data and more demanding parameters, TI appears to be a more complex tool than REW for field water supply diagnosis in forests.
